morningman opened a new pull request, #22666: URL: https://github.com/apache/doris/pull/22666
## Proposed changes Issue Number: close #22429 For load request, there are 2 tuples on scan node, input tuple and output tuple. The input tuple is for reading file, and it will be converted to output tuple based on user specified column mappings. And the broker load support different column mapping in different data description to same table(or partition). So for each scanner, the output tuples are same but the input tuple can be different. The previous implements save the input tuple in scan node level, causing different scanner using same input tuple, which is incorrect. This PR remove the input tuple from scan node and save them in each scanners. ## Further comments If this is a relatively large or complex change, kick off the discussion at [[email protected]](mailto:[email protected]) by explaining why you chose the solution you did and what alternatives you considered, etc... -- This is an automated message from the Apache Git Service.
